Leaving doors open while climate control runs is a wasteful practice that can push electricity use higher by roughly a fifth, according to statements from government officials. Agnes Pannier-Runacher, the Minister of Ecological Transition, described the habit as impractical in a recent interview with a major French weekly publication.
As hotter conditions swept across the country, bringing record temperatures in many regions, the government signaled a plan to expand existing restrictions nationwide. Prior bans had been implemented in cities like Paris and Lyon, and the current heat wave intensified calls to broaden the scope. A financial consequence cited in the discourse is a penalty around 750 euros for noncompliance under extended rules.
Regarding the prohibition on illuminating billboards and shop windows, enforcement has been strongest in smaller cities with populations under a few hundred thousand. Between 1:00 and 6:00, nonessential lighting is restricted, with larger municipalities carrying additional local regulations.
If the national rollout continues, the government has indicated a higher potential penalty of 1,500 euros and a more uniform framework. Exceptions are expected for critical hubs such as train stations and airports that remain operational.
Cuts in unnecessary consumption
Pannier-Runacher emphasized a cooperative approach, engaging companies across sectors to cut back on nonessential energy use. A notable example occurred in the distribution sector in France last week, with a formalized “crisis energy protocol” slated to begin on October 15 to curb electricity demand.
The protocol outlines concrete steps, including keeping store heating at modest levels, turning off internal lighting when spaces are unoccupied, and reducing lighting intensity during operating hours. These measures aim to lower electricity draw without compromising safety or service quality.
Additional measures are being explored, such as tracking generator capacity and maintaining ongoing dialogue with the highest energy-consuming sectors to prevent power interruptions in the winter season.
Officials stress that all actions are designed to minimize the risk of outages. Citizens and businesses are encouraged to stay informed about consumption patterns. Energy providers may also implement pricing that nudges households and enterprises toward lower use during peak times.
At present, the government does not foresee immediate reductions in traffic speeds. The maximum highway limit remains a matter of policy review rather than a mandated change, with current guidance arising from international energy bodies that advise modest adjustments during peak stress.
These efforts unfold as France and the European Union prepare for broader actions aimed at reducing energy dependence on external suppliers in light of potential disruptions to gas imports. The broader objective is to strengthen resilience across the energy system while supporting households during months of rising bills.
In smaller communities like Parmain, a town of about 6,000 near Paris, authorities have already turned down public lighting between 1:15 a.m. and 4:30 a.m. and have lowered indoor temperatures to match reduced outdoor demand. The town also reduced its heated pool temperature by a few degrees to further ease energy consumption.
